The calendar says we still have 11 days of summer left, but many Iowans are switching on their furnaces as fall-like temperatures are arriving early. Tonight, Iowans living in the northern half of the state may want to cover their outdoor flowers and tender vegetation. National Weather Service Meteorologist Kevin Skow says there’s the potential for frosty conditions.

Skow says, “Tonight, as skies clear out and we have that cold, northerly wind and the winds become light towards morning, that could result in temperatures dropping down into the mid-30s, again across northern Iowa, which could result in some areas of frost.”

Skow says the area north of Highway 30 could see frost in the low-lying areas early Saturday. He says the weekend should be pleasant, with a slight warm-up. “Highs will rebound to the low 60s for Saturday and upper 60s for Sunday so thankfully, our shot of cold air won’t last too long,” Skow says. “We’ll be back up closer to what we call average for this time of year by the end of the weekend.”

Forecasters say there is also a possibility of more showers Sunday evening. See the full forecast at www.weather.gov.
